"What the hell is the ranking member of the Senate Foreign Relations Committee doing taking any money at all from lobbyists?" he asked.

Hilton also blasted Menendez for the claims made in his recent federal corruption trial. While the trial ended in a hung jury, the Democrat was admonished by the Senate Ethics Committee over the allegations.

In 2015, Menendez was indicted in connection with allegations he took free rides on a wealthy ophthalmologist donor's private jet and received free lodging in the Floridian's home in the Dominican Republic.

Menendez reacted to the mistrial, telling reporters that "[c]ertain elements of the FBI and of our state cannot stand, or even worse, accept that the Latino kid from Union City and Hudson County could grow up to be a United States senator and be honest."

"I've made my share of mistakes, but my mistakes were never a crime," Menendez said at the time.

"Even Democrats are distancing themselves from Menendez," Hilton said, pointing to a New York Post cover that dubbed him "Toxic Bob" and surmised that New Jersey Gov. Phil Murphy's (D) trip abroad suspiciously coincided with the senator's reelection bid.

Hilton said that Menendez, whom he called a swamp "monster," does not deserve another term.
